The Eng-Tips staff will check this out and take appropriate action. WillisV, Agreed, this makes sense to me despite being a mechie. We just recently designed some lifting lugs where the dimensions were pretty much set by the client.
Hi Dik, That’s correct. Provides minimum structural and mechanical design and electrical component selection criteria for ASME B I also need to determine this for a flexion analysis in the weak axis. Any help would be appreciated.

Defense manufacturing is all about project manufacturing and project accounting. Instead, you’re checking for a glocal buckling Lateral torsion buckling mode of the plate. For now, I am working on a single case and detailing the calculations. The problem I have is that it’s not clear to me if I am dealing with a compact or non-compact section as per table Posting Guidelines Promoting, 0208, recruiting, coursework and thesis posting is forbidden.
Aske All, Thanks 20088 your help. Even then, I wonder about how much compression would even get into the lug with an angled hanging “tensile” load. Are you an Engineering professional? JAE, Still good advice, since I am doing the calcs in Mathcad to semi-automate the design, I am still going to check the section for it’s compactness, however there’s also a simplified clause for rectangular assme I will check out.

The base of my lugs will be wider, however, to be conservative I am designing with a constant width plate for now. Already Subscribed to this document.

Hi Everyone, Baseed on thread Almost invariably, pin bearing, shear and yielding in the area of the pin, and good quality welding detailing controls the design of lifting lugs.
I’m not sure LTB of a lug could ever happen unless you had a really funky looking lugI would probably just use the full bthh capacity of the pad eye. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Register now while it’s still free!

The next available drill size will be used to make the hole slightly larger than the pin. You’ll see that there is no criteria for checking whether the section is compact or non-compact. Alternatively, I will survive without see it.

The provisions in this Standard apply to the design or modification of below-the-hook lifting devices. For a square plate, like your lug, local buckling is not possible.

Their thickness is generally driven by bearing checks on the pin hole that make this plate much much stockier than typical structural elements. I have never seen a lifting lug that would not be classified as compact by a long shot.
